Pavement Management for Airports Roads and Parking Lots PDF

Pavements need to be managed, not simply maintained. Although it is difficult to change the way we do business, it will be more difficult to explain to future generations how we failed to manage our resources and preserve our infrastructure.

When asked for reasons why they did not use the latest in pavement management technology, pavement managers gave many answers.
“The only time I have is spent fighting fires.”
“We normally use a 2-inch overlay.”
“Just spray the pavement black at the end of the year.”
“I can’t afford to do inspections; I’d rather use the money to fix the pavement.”

Managers and engineers who have adopted pavement technology understand that pavement management is a matter of “Pay now, or pay much more later.”

Agencies are finding that they cannot afford to pay later; it is more costly to rehabilitate badly deteriorated pavements.

Unfortunately, the pavement infrastructure managed by some agencies is at a point where a large sum of money will be needed for restoration. Agencies blessed with a good pavement infrastructure need to start a pavement management system as soon as possible.

They need to: inventory the pavement infrastructure, assess its current and projected condition, determine budget needs to maintain the pavement condition above an acceptable level, identify work requirements, prioritize projects, and optimize spending of maintenance funds.

The primary objective of this book is to present pavement management technology to engineering consultants, highway and airport agencies, and universities.

Planning and Design of Airports Fifth Edition PDF

In the 16 years since this last update, it may be said that the changes to the practice of airport planning and design have been more significant than in any other era in the history of aviation.

Implementation of twenty-first-century technologies has resulted in the first major overhaul to aircraft and air navigation systems in generations, computer-based analytical and design models have replaced antiquated monographs and estimation tables, and highly significant geopolitical events have all but rewritten the rules of
planning, designing, and operating civil-use airports.

These significant enhancements to the aviation system have resulted in unique challenges in creating an updated fifth edition of this important and highly accepted text. While every attempt was made to keep to the traditional structure of the book and to preserve the theoretical strengths for which it is most well known, much of the material in the previous edition required more replacement than simply being made current.

Within this latest edition the reader will find, for example, new and entirely different strategies to estimate required runway lengths and their associated required pavement thicknesses. This text attempts to maintain the flavor of previous editions while understanding, for example, that airport navigational aids of the previous century are becoming all but obsolete, in favor of a digital, satellite-based communication and navigational system, and that airport financing strategies are in a revolutionary state, given anticipated changes to federal aviation funding mechanisms.

Updating this edition has, in fact, been a continuous “race against time,” as important changes to the aviation system were constantly occurring during the process.
